Authors: Nauchi M, Sakai T, Yamawaki M, Ito Y Abstract A 78-year-old woman had paroxysmal atrial fibrillation and effort angina. Two months before she was admitted for a coronary angiography, she had been feeling dizzy. A Holter 24-hour electrocardiography monitor exhibited an asymptomatic episode of 2.9 seconds of RR interval. She underwent a coronary angiography, which showed intermediate stenosis in the left descending artery. Fractional flow reserve (FFR) measurement using intracoronary papaverine administration was performed. After intracoronary papaverine (12 mg) administration, pause of 4 seconds led to poly...

This article reviews the evidence for and against these drugs, alternatives treatments for refractory VF/pVT and aims to define the role of antiarrhythmic drugs during cardiopulmonary resuscitation (CPR). Recent findings A large randomized controlled trial that compared amiodarone, lidocaine and saline 0.9% sodium chloride for the treatment of refractory VF/pVT out-of-hospital cardiac arrest reported no difference in survival to hospital discharge or neurological outcome. In patients with witnessed arrest, survival was improved with antiarrhythmic drugs compared to saline. Summary The benefit of antiarrhythmic drugs ...

Intraoperative cardiac arrest (CA) is usually attributable to pre-existing disease, or to intraoperative complications. In rare cases, intraoperative stress can demask certain genetic diseases, such as Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT). It is essential that neurosurgeons are aware of the etiologies, risk factors, and initial management of CA during surgery in the prone position.

Discussion Wide QRS complex tachycardia with a rate of around 225/min. Wide QRS tachycardia is to be taken as ventricular tachycardia until proved otherwise. Monophasic negative wide QRS complexes are seen from V1-V5. V6 shows positive wide QRS complex with LBBB morphology. Similar morphology is seen in leads I and aVL as well. The QRS voltages are low in limb leads. Lead II shows multiple irregularities in P waves which could be dissociated P waves. The atrial rate calculated from the dissociated P waves seems to similar to that of the tachycardia rate, though one cant be very sure as to which irregularities are P waves a...

ConclusionThese results suggest prophylactic catheter ablation decreases ICD therapies, including shocks and electrical storm with no improvement in overall mortality. There is a need for future carefully designed randomized clinical trials.

Colchicine ingestion is rare but highly lethal. Patients usually die of multiorgan failure and cardiogenic shock. Colchicine is not only associated with depressed myocardial function but also with fatal heart rhythm disturbances, such as complete heart block, ventricular tachycardia, and asystole. While histologic changes of myocytes are well known, the mechanism by which colchicine affects cardiac impulse generation and conduction is not fully understood.

CONCLUSIONS: The change in FT morphology during ablation may be associated with a change in clinical course when shifting from one route to another and may aggravate symptoms. Targeting of the proximal conduction system (such as bifurcation, LPF, left anterior fascicle, high septal/auxiliary pathway) may serve to solve this problem. PMID: 29658207 [PubMed - in process]
